Move your camera up  - we don't need to see the chairs... right? Moving the camera up gives you more space on top for the caption boxes and dialogue balloons. Since the chairs aren't the subject of the scene you're not losing anything.

Swivel your zOrbit of your camera - it will create even more room on the right or left top section of your shot and the human eye is fooled into thinking there's motion occuring.

If the main character is speaking, have their mouth open a bit more.

great scene shot.

Prime membership is fantastic! So is Platinum Club and grab a Poserworld membership too. All these stores are fantastic.

Looking forward to your future works.
